    All games should benefit in performance from DirectX 12 API even though they may not support the features.

    I just disabled it and it doesn't revert back to 12 - still at 11.3 according to dxdiag.

    EDIT: You are right. I accidentally disabled it in a game instead of globally.

    MFAA worked fine in the preview and 12.

    DxDiag shows 11.2 for me, I'm running a GTX 550 Ti... however, in the Nvidia Control Panel it says DirectX 12 for the Runtime version and the Direct3D API version. However, the Direct3D Feature Level says 11.0.

    I'm running driver version WHQL 353.62, which was released today.

    I didn't have to install any games at the moment... I remember when you could often times skip DX installations for games... or the installer didn't install anything if it detected something newer on your machine.

    I dont think Fermi (500series cards) support DX12 yet from nvidia. I think its kepler upwards (600 Series).
    You can read bout it there will be support soon for them.
